Supermassive Black Holes

Supermassive black holes are incredibly dense regions in the center of galaxies, with masses that can be millions or even billions of times that of the sun. These mysterious objects have fascinated scientists and astronomers for decades, and continue to be a subject of intense study and research.

Characteristics of Supermassive Black Holes

Supermassive black holes have several key characteristics that set them apart from their smaller counterparts:

• Size: Supermassive black holes are significantly larger in size compared to stellar black holes, with diameters reaching millions of miles.
• Mass: They have masses ranging from millions to billions of times the mass of the sun.
• Formation: The exact formation mechanism of supermassive black holes is still a topic of active research, but they are thought to grow through mergers with other black holes and by accreting mass from their surrounding environment.
• Galactic Center: Supermassive black holes are typically found at the center of galaxies, including our own Milky Way.
